I wanted to ask you about the desktop part of the technology.
If the documentation is about how ordinary developers can inject native code into a desktop application (WPF, Mac, Linux) like buinding or as a custom plugin or something similar
Best regards, Vadim
You have all the same options for platform code on desktop that you do on mobile:
Adding it directly to the native runner app that's created by flutter create
Writing a plugin
FFI

So, I'm thinking of creating a CLI application that could also be used with UI, developed in Flutter.
The idea is that there would be 3 different packages, one for the business logic, one for the CLI and one for the Flutter app. Is there a way to import the Flutter app as a dependency in my CLI package, so I could open the Flutter app from the CLI? If so, how would I do it?
Seems like you want to use 1 library containing the business logic for 2 different applications: Desktop CLI app and mobile app (android/iOS).
It's very much possible with flutter. By default flutter installs only the android and iOS platform supports but by changing few configurations in installed flutter SDK we can extend the same setup to Web and Desktop apps (Windows, MacOS or linux) as well.
Check this official doc for enabling desktop support
Check this official doc for enabling Web support
You can enable these settings in your existing application only.
Can you guys tell me what all these different projects means?
New Flutter Project
Because I can't find the documentation anywhere
So if you can find the reference it will help me
Flutter Application: A fully-functional standalone Flutter application.
Flutter Plugin: A plugin is a kind of bridge that you develop between a native feature like camera API in Android and iOS.
Flutter Package: A package is a flutter application written solely using Dart. It doesn't have much to do with the Native functionalities.
Flutter Module: A module is a set of functionalities that you want to use in your app. It is a custom code that does a specific task but can be used for other apps in the future. So, you keep it handy. In other words, this module can be integrated in other apps too.
I want to know that if it is possible to make flutter app for web without using HTML, css or javascript and only using flutter and dart
Yes, it is absolutely possible to create a web app using flutter and dart.
To add web support in the existing flutter project you can run the command flutter create . and to release it run the command flutter build web
For testing your app in chrome you can use command flutter run -d chrome
You can disable android support using command flutter config --no-enable-android and disable ios support using command flutter config --no-enable-ios
Yeah, it is not need to build web app with HTML,CSS & JS, your flutter code alone will work.
Note: try flutter upgrade bcs v-2.0.0 stable release for web got released
Yes, you can use Dart/Flutter exclusively to build web apps. You don't need to write any HTML/CSS/Javascript.
You can setup your project from the terminal (like previous comments suggests), or you can use an IDE such Android Studio, or you can use Visual Studio.
If you use Android Studio, you can create a new Flutter Project, and select the 'web' platform only, and de-select Android and IOS.
I am currently using Dart/Flutter to build web apps only. Android Studio builds the HTML/CSS/Javascript for you. Then you just have to publish it into a web server (online or local).
Yes you can use Flutter for web apps but though it is in early stage of development about how the web app will be stable or not
i'm working on a task for detecting USB connected devices (printers) for Flutter desktop application. I found many plugins but they are not working on desktop app. The code throws exception in detecting list of connected USB devices The exception it throws is
No implementation found for the method listDevices for the channel usb_serial
How i can change that plugin for desktop, to find USB connected devices/or any other solution?
By definition, a Flutter plugin has native code for each platform. That error is because you're using a plugin that has not been implemented for your platform.
The way you would change the plugin to make it work would be to write an implementation of that plugin's native code for each desktop platform you want to add support for.
You need to write some c++ code, and see if you can find some native usb lib to make calls on.
I am learning flutter right now and want to know which platforms support flutter applications.
I know that flutter supports iOS and Android.
I want to know if we can run flutter programs on windows.
Flutter Desktop: currently this effort is still under way
Google has an example project project.
About Flutter on Windows:
The current Windows shell is a GLFW placeholder, to allow early
experimentation. It will be replaced in the future with a Win32 or UWP
shell that allows view-level embedding of Flutter within an
application.
Expect the APIs for the final shell to be radically different from the
current implementation.
